I'll let you know in 2 years. I have a whole bunch of very cold-hardy varieties in my little collection. Not Ichang papeda, but I believe most of them do have cold-hardy papeda going back in their ancestry. When they become more established I was thinking about sending out seeds and letting other citrus hobbyists find out what types of fruits they produce. Then maybe we could find interesting new varieties without me having to sprout the seeds and take care of all those trees myself. It's really luck of the draw what genes the seeds will get.
